Nita gana $ 20 por semana paseando al perro de su vecino. También gana $ 2 por cada rosa que vende de su jardín de rosas. Nita q
Rudik [331]

Answer:

La situación está representada por el siguiente sistema:

y = 20+2\cdot x

y \ge 50

Donde:

x - Cantidad de rosas vendidas semanalmente.

y - Ganancia semanal, medida en dólares.

Step-by-step explanation:

De acuerdo con el enunciado, Nita gana una cantidad fija cada semana por pasear al perro de su vecino, con un monto de $ 20, mientras que gana en función de la cantidad de rosas a vender, con un valor unitario de $ 2. Si ella desea ganar al menos $ 50, por tanto, se requiere construir el siguiente sistema, conformado por una ecuación y una inecuación:

y = 20+2\cdot x (1)

y \ge 50 (2)

Donde:

x - Cantidad de rosas vendidas semanalmente.

y - Ganancia semanal, medida en dólares.

The coordinates of point A are (p, q) and coordinates of point B are (p+2q, q+2p). Provide your complete solutions and proofs in
Dafna1 [17]

Answer:

The mid-point (p + q , q + p) of AB is the same distance from the x-axis and the y-axis

Step-by-step explanation:

*<em> Lets explain how to solve the problem</em>

- Any point will be equidistant from the x-axis and the y-axis must have

 equal coordinates

- Ex: point (4 , 4) is the same distance from the x-axis and the y-axis

 because the distance from the x-axis to the point is 4 (y-coordinate)

 and the distance from the y-axis and the point is 4 (x-coordinate)

- If (x , y) is the mid-point of a segment its endpoints are

 (x_{1},y_{1})  and (x_{2},y_{2}), then

 x=\frac{x_{1}+x_{2}}{2} and y=\frac{y_{1}+y_{2}}{2}

* <em>Lets solve the problem</em>

∵ Point A has coordinates (p , q)

∵ Point B has coordinates (p + 2q , q + 2p)

- The mid-point of AB is (x , y)

∵ x=\frac{p+p+2q}{2}

∴ x=\frac{2p+2q}{2}

- Take 2 as a common factor from the terms of the numerator

∴ x=\frac{2(p+q)}{2}

- Divide up and down by 2

∴ x = p + q

∵ y=\frac{q+q+2p}{2}

∴ y=\frac{2q+2p}{2}

- Take 2 as a common factor from the terms of the numerator

∴ y=\frac{2(q+p)}{2}

- Divide up and down by 2

∴ y = q + p

∴ <em>The mid point of AB is (p + q , q + p)</em>

- p + q is the same with q + p

∵ The x-coordinate of the mid point of AB is p + q

∵ The y-coordinate of the mid point of AB is q + p

∵ p + q = q + p

∴ The coordinates of the mid-point of AB are equal

- According the explanation above

∴ The mid-point (p + q , q + p) of AB is the same distance from the

   x-axis and the y-axis

What percent of 80 is 12?<br><br>what number is 75% of 52? ​
HACTEHA [7]

Answer:

<em>The answer for the first question is: </em>

<em>12/80 =</em>

<em>12 ÷ 80 =</em>

<em>0.15 =</em>

<em>0.15 × 100/100 =</em>

<em>0.15 × 100% =</em>

<em>(0.15 × 100)% =</em>

<h2><em>15%</em></h2>

<em>Then, the answer for the second question is: </em>

<em>75% × 52 =</em>

<em>(75 ÷ 100) × 52 =</em>

<em>(75 × 52) ÷ 100 =</em>

<em>3,900 ÷ 100 =</em>

<h2><em>39 </em></h2>

* Hopefully this helps:) Mark me the brainliest:)!!!
